Installation Notes and Tips

Verify the inlet and outlet pipe sizes, core dimensions, and vehicle fitment before installation. Proper cooling-system draining, flushing, and refill procedures help protect the replacement heater core and support stable heater operation after service. Confirm the HVAC system is free of debris or contamination that could restrict flow through the new core.
